NIS A. J'UHL, OF CHICAGO, ILLINOIS.

To all whom it may concern:

Be it known that I, N IS A. JUIIL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in \Veather Strips, of Which the following is a specification.

This invention relates to weather-strips for windows, and more particularly a device of this kind which is applicable to the lower sash of the window to exclude drafts at the ends of the top rail of said sash, the device being constructed and arranged to effectively pack or Seal the spaces between the sash and the window frame, and also the ends of the meeting rails of the sashes.

The invention has for its object to provide a simple, cheap and efficient device of the kind stated, and also one which can be easily applied.

The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing- Figure l is a perspective view of the device applied to the window;

Fig. 1 is an elevation thereof with parts broken away, and

Fig. 3 is a perspective view of the device detached.

Referring specifically to the drawing, 5 denotes the top rail of the lower sash of a window. The sash is slidably mounted in a groove in the window frame formed by the parting strip 6 and the molding strip 7 mounted on the pulley stile 8. This is an ordinary window frame structure and a detailed description thereof is therefore not necessary. One of the stiles of the upper sash is shown at 9. The sashes are counterweighted as usual, the sash cord of the lower sash being shown at 10.

In order to provide a weatherproof joint between the window frame and the end of the sash rail 5, and also between said rail and the sash stile 9, there is provided a Weatherstrip constructed and arranged in a manner which will now be described. It will be understood that each end of the lower sash is equipped with one of these weather-strips, and as they are alike, a description of one suflices for both.

WEATHER-STRIP.

Patented Jan. 22., rare.

Serial No. 156,891.

lnv improved weather-strip is composed of a sheet 11 of rubber, felt, or other suitable flexible packing material, and a rigid backing plate 12 of sheet metal or other stilf materia The packing plate 11 has two of its adjacent edges 13 and 14 arranged at a right angle to each other and connected by a curved edge 15, the plate being therefore substantially quadrantal. At the junction of the straight edges 13 and 1 1, the plate has an angular recess 16, and each of said edges has, intermediate its ends, a recess 17 which is substantially semicircular and from which extends a slit 18, said slits being made in the body of the plate.

The backing plate 12 is shaped to correspond to the general contour of the packing plate 11, but it is slightly smaller than the latter, so as to leave the edge portions there of uncovered and projecting. The two plates are fastened together by rivets or other suitable means 19.

In use, the device is placed on top of the rail 5, at the end thereof, which is inclosed in the parts 6, 7 and 8, and it may be secured to the rail in any suitable manner, as by screws 20. lVhen in proper position on the rail 5, the edge 13 of the packing plate 11 seats against the face of the stile 8, and the edges of the recess 16 seat against the inner and outer faces of the strip 6. The edge 14 seats against the inner face of the sash stile 9. The recess 17 in the edge 13 receives the sash cord 10 to close up the space around the same. At the junction of the edge 15 with the edges 13 and 14:, the former has short straight portions 21 extending at right angles to the latter edges. The edge portion 21 joining the edge 13 seats against the inner edge of the strip 7.

It will be evident from the foregoing that the spaces between the end of the rail 5 and the parts which it slidably engages are completely closed up with the exception of that part of the stile 9 which is opposite the recess 17 in the edge 14. However, this recess is so small that the efficiency of the device is' not affected to an appreciable extent.

It will be noted that the edge 1 1 is longer than the edge 13, in view of which the device may be applied to two different sized windows. For a window larger than the one shown, the device will be so positioned on the rail 5 that the edge 14 engages the pulley stile 8, and the edge 13 the sash stile 9.

The edge portions of the plate 11 are free of the plate 12 so that they may readily flex and remain in sealing contact when the lower sash is slid.

The edge portions of the backing plate 12, coinciding with the edges 13 and 14 of the packing plate 11, have downward bends to seat squarely or impinge on top of said plate and hold the same firmly down against the rail 5.

The device is simple and inexpensive, it can be easily applied without any changes in the structure of the window, and it eifectually serves the purpose for which it is designed.

1 claim:

1. A weather-strip-for Windows comprising a flexible packing plate and a backing plate secured thereto, the packing plate having edge portions which project from the edges of the backing plate, there being two; adjacent ones of such edge portions arranged at a right angle to each other and having different dimensions, with an in- 1 wardly directed recess at the corner of said edges, and each of said edges having sash cord receiving recesses intermediate their ends, said packing plate also having projecting edge portions at the outer ends of each of the aforesaid edge portions and extending at right angles thereto.

2. A weather-strip for Windows comprising a flexible packing plate and a backing plate secured thereto, the packing plate having; edge portions which project fron vthe edges of the backing plate, there being two adjacent ones of such edge portions arat a right angle thereto to seat against one of the side walls of the groove,- the parting strip of the window framebei'ngreceived within the aforesaid recess, and the other one of the aforesaid edge portions being positioned to engage one side'of tne stile of the other sash, the edge portions of the backing plate corresponding to the aforesaid edge portions of the packing plate be ing downwardly directed to impinge on the packing plate. In testimony whereof I afiix my signature.
